LUBRIcANT-DrsTRIBUTER.

Application filed December 11, 1908.

Specification of Letters Patent.

Patented April 20, 1909,

Serial No. 466,943.

To all whom it may concern:

Be it known that I, NEWTON McKee, a citizen of the United States, and a member of the National Home for Disabled Volunteer Soldiers, at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Lubricant-Distributors, of which the following is a specification.

My invention relates to improvements in lubricant distributers for bearings.

The object of my invention is to provide an improved form of construction, with especial reference to the maintenance of a continuous circulation of lubricant when the shaft is turning.

In the following description, reference is had to the accompanying drawings in which` Figure 1 is a longitudinal sectional view of a bearing embodying my invention. Figs. 2 and 3 are cross sectional views drawn respectively on lines :cha and @/-fy of Fig. l. Fig. 4 is a plan view with the upper portion of the casing removed.

Like parts are identified by the same reference characters throughout the several views.

The shaft 1 extends through a bearing box 2 having central laterally projecting trunnions 3 which rest in sockets formed in the chair 4. A casing or housing member 5 covers the bearing, and is secured to the chair by bolts 6. At each side of the trunnions 3, the bearing box is encircled by oil carriers 10 preferably comprising collars of larger diameter than the box and formed of comparatively thin material. The lower portions of these collars are submerged in oil 25 contained in an oil cavity 26 in the lower portion of the chair. A sleeve 27 at each end of the box, is secured to the shaft by a set screw 19 exterior to the casing, and within the casing, is provided with an annular iiange 7 having one or more arms 8 adapted to engage a projection 9 on the corresponding oil carrier 10, whereby the latter is caused to rotate with the shaft and carry up oil from cavity 26 to the top of the box, where it is scraped from vthe inner surfaces of the collars 10 by a scraping wing 11 common to both collars. This wing is seated in a longitudinal lrerf in the bearing block 2 and is provided with a centrally disposed fin 28 which serves as a spacer for the carriers 10. The oil scraped from the carriers, is received by channels 29 in the bearing block, (one on each side of the wing 11), and directed into a cavity 12 from which it is fed to the shaft through ducts 13 which extend inwardly through the body of the box 2 and a Babbitt metal bushing 30 which is interposed between the shaft and the box.

Access is afforded to the bearing through openings 15 in the casing 5 which are normally closed by suitable covers 16 connected by chains 17 to any suitable point of attachment to prevent them from becoming lost. A drain plug 18 is employed for removing the oil when cleaning the bearing.

ln the drawings, l have shown four arms 8 on each of the flanges 7. The object of using a plurality of arms is to insure a prompt engagement of projection 9 when the shaft commences to rotate and before speed is attained, which might otherwise damage the carrier. The sleeves 27 are also preferably provided with dust excluding collars 20 which bear against the inner wall of the chair 4 and housing 5 and also prevent the oil from escaping. p

Guide bands 14 are preferably employed which are secured at their ends between the chair and the casing 5 and extend in the form of arches over the carriers 10 to prevent them from lifting. The carriers are preferably provided with perforations 21 which permit oil to pass within the carrier in addition to that received at the ends. The form of these perforationsis not material. An oil groove 31 is preferably formed in the Babbitt metal bushing 30.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent is,-

' 1. In a bearing, the combination with a shaft and bearing member, of a member inclosing the bearing member and provided with an oil chamber, a carrier encircling the bearing member with its lower portion in the oil chamber, connections for actuating said carrier from the shaft, and means for conveying oil from the upper portion of the carrier to the shaft within the bearing.

2. Ina bearing the combination with a shaft and bearing member, of a member inclosing the bearing member and provided with an oil chamber, a carrier encircling the bearing member with its lower portion in the oil chamber, means for actuating the carrier, and a scraping device for removing oil from the upper portion of the carrier said bearing member being provided with oil ducts adapted to convey oil 'from the scraping device to the shalt Within the bearing member'.

3. In a bearing the combination with a shaft and bearing member', ol' a member inclosing the bearing member and provided with an oil chamber, a carrier encircling the bearing member with its lower portion in the oil chamber, means for actuating the carrier and a scraping device l`or removing oil from the upper portion oi the carrier said bearing member being provided. with oil ducts adapted to convey oil from the scraping device to the shaft Within the bearing member together with oil retaining collars connected with the shaft and arranged to bear against the inclosing member at the sha'lt openings.

4. In a bearing, the combination with a shaft and bearing member, oi' a set oi rotary carrier collars encircling the respective ends oi' the bearing member, an oil reservoir in which said collars dip and a scraping device 'for removing oil from said collars, said bean ing member being provided With oil ducts and channels leading to the shaft from points adjacent to the scraping member.

5. In a bearing, the combination With a shaft and bearing member, oi a set of rotary carrier collars encircling the respective ends oi the bearing member, an oil reservoir in Which said collars dip, and a scraping device 'l'or removing oil 'from said collars said bearing member being provided. With oil ducts and cb annels leading to the shaft l'rom points adjacent to the scraping member together with sleeves fast on the sha'l't and provided with radial arms engaging said carrier collars at the respective ends of the bearing member.

6. In a bearing, the combination with a shal't and bearing member, ol' a member inclosing the bearing member and provided with an oil chamber, a carrier incircling the bearing member with its lower portion in the oil chamber, connections lor actuating said carrier from the sha'lt, and means for conveying oil from the upper portion o'lI the carrier to the sliai't Within the bearing together With arched guides extending over the upper surfaces ol the cai'1'iei,-said bearing member being provided with trunnions soclreted in the chair.

In testimony Whereo'l' I aHiX my signature in the presence oi' two Witnesses.
